Jun 23, 2013 · Trees come in the category of DAG : Directed Acyclic Graphs is a kind of directed graph that have no cycles. Graph can be Cyclic or Acyclic. Different Types: Different types of trees are : Binary Tree , Binary Search Tree, AVL tree, Heaps. There are mainly two types of Graphs : Directed and Undirected graphs. Applications
Binary search can be performed on a sorted array. In this approach, the index of an element x is determined if the element belongs to the list of elements. If the array is unsorted, linear search is used to determine the position.
However, average access time-complexity in a hash table is definitely O(1). That's the whole idea of a hash function! The worst-time complexity is O(n). In a binary search tree, the average run-time complexity time is simply O(log(n)), I don't know where BigKdotAtkTdot got that n from. Perhaps he means O(m*log(n)), where m is the maximal string length.
An optimal binary search tree is a binary search tree for which the nodes are arranged on levels such that the tree cost is minimum . For the purpose of a better presentation of optimal binary search trees, we will consider "extended binary search trees", which have the keys stored at their internal nodes.
• Describe and implement a variety of advanced data structures (hash tables, priority queues, balanced search trees, graphs). • Analyze the space and time complexity of the algorithms studied in the course. • Identify different solutions for a given problem; analyze advantages and disadvantages to different solutions.

I know that in a normal binary tree, the time complexity for deletion is O(h); O(n) worst case and O(logn) best case. But since we are replacing the key of the deleting node by the minimum node of right sub tree of it, it will take more time to find the minimum key.

A species tree S with a relative time order on its vertices (i.e. 0 is the present time and vertex c is at time 2). The three arrowed dotted lines represent transfers between two branches of S and the arrows their directions [e.g. T1 has branch (c, d) as donor and (b, e) as receiver].
Binary search trees. A binary search tree is one in which every node n satisfies the binary search tree invariant: its left child and all the nodes below it have values (or keys) less than that of n. Similarly, the right child node and all nodes below it have values greater than that of n. The code for a binary search tree looks like the following.
Bayes Optimal Classiﬁcation for Decision Trees which wedevelopedthe DL8algorithmfordetermining one tree that maximizes accuracy (Nijssen & Fromont, 2007). DL8 is based on dynamic programming on a pre-computed lattice of itemsets, and scans these itemsets decreasing in size. Its time complexity is lin-ear in the size of the lattice.
